I like rules-light larps and I like larps where abilities can be resolved in real time without needing an artificial mechanic like paper-scissor-rock or some kind of card system.
Combat is reasonably simple to physically represent in larp because we can all take out our latex swords and if you get hit, you're wounded. The game can be played in real time, without needing time-stops or special cards. The mechanic is simple: if you hit someone, they are wounded. If they dodge, or parry, they are not hurt.
I'm looking for a mechanic that can be used for magic and 'contest of will' type situations that can flow as well as combat does. I'd like magic to have the same flow as combat with some kind of 'attack' and 'defence' that the players can act out.
I know there are systems where people compare scores ("I have 5 will power, I cast charm" --> "I have 6 will power, I resist") but I'm not interested in that kind of system. The system doesn't need to cater to a variation of skill levels. It can be like simple larp combat where the skill (or will power) of the player is what matters.
I thought of using something like a staring contest (first one to blink loses) but I thought I'd also see if existing systems already had a mechanic.
Thanks in anticipation!
